Embeddings

Numerical representations that capture meaning

What is Embeddings?

Numerical vector representations of text, images, or data that capture semantic meaning and relationships. Words with similar meanings get similar vectors, enabling machines to understand that "crypto" and "blockchain" are related. Embeddings power semantic search, recommendation engines, and RAG systems, they're the foundation that makes modern AI useful for finding and comparing information.

How it works

Embedding space: meaning as distance

Key takeaways

  • Converts text into fixed-length number arrays

  • Semantic similarity = spatial proximity

  • Foundation for search, clustering, and RAG

▸

Real-world example

The sentence 'I love this product' and 'This item is amazing' have nearly identical embeddings even though they share almost no words. This is how semantic search finds meaning, not just keywords.
